i onsonnunrunnrivn parts whereby the frictional resistance to the operation will be decreased and. the speed and consequent powerfof ythe rotor obtained from a given charge will be increased.

More speciically stated, the object lof the invention is to provide novel means whereby the velocity of theY exploded gases in escaping from the compression and explosion chamber will be utilized by the impact of said gases to impart motion to the rotor.

Another object of the invention is to provide novel means whereby fuel will be continuously supplied and compressed and then exploded so as to act successively upon different points of the periphery of the rotor whereby, to vimpart a continuous rotary motionv thereto. J A j' Other incidental' objects of the``invention will appear as the description'of the same proceeds and the novel features 'will be particularly pointed out in the claim following the detailed description. l

lin the= annexed drawing, I have shown av sectional elevation of an engine embodying the principles of my invention.

ln carrying out my invention, employ a rotor l and a housing therefor, indicated at 2, which may be of any desired construction and dimensions, the rotor being secured to a shaft 3 mounted in suitable bearings upon the casing and beingl so' proportioned that the clearance between the periphery of the rotor and the inner circumference of the stator or casing will be just sufficient to pref vent the rotor binding against the stator. The stator or casing is constructed with pluralities of ports 4 at various points around its periphery, which' ports are dis-A posed approXimately tangential to the rotor so that the gases' passing through said ports Specification of Letters Patent.

will be directed againstthe vanes of the rotor Vand by their impact upon said vanes will vdrive the rotor. Spaced from the-ports open to the atmosphere or lead into conduits or pipes by which the vapors may be conveyedto any desired point. In the present 'instance, ll have illustrated two sets of ports lbut it is lto be understood that a greater vnumber of sets maybe employed, the vnum-y ber depending upon theV size of .the engine andtheuworl for which itis designed. In'

order tosuccessfullygapply the principles of.

myinvention, however, atleast two sets of v4l are outlet or exhaust ports 5 which may portsvinust beprovided and each set ofports i must', register :perfectly with .the exhaust ports (S1-in thegside off; a cylinder 7i Within a i A'lo each cylinder 7 is mountedgaHpiston 8 and the 4stroke-of th-ispistonlshouldbeso regulated r that, when the? piston is yat .the inner limito-f its movement,`its innerend will be directly'over thatport 6 n earestthe,adja-4 cent end of the cylinder so that,when' lan explosion occurs, the piston will *at once,`

uncover an Aoutlet port and permit the "gases to immediately flo-w to and against'fthe rotor.

A piston rod 9 'extends from'each 'piston through the end of a cylinder andhas its outer end supportedby the end of ayoke l0` which is secured' upon the end of the cylinder. Between the end of the yoke and astop l1 on the piston rod is coiled a sprin l2.which, by its expansion, tends to hold the piston over the ports 6. stops 1l at various points along ythe piston rod, the tension of the spring Al2 maybe adjusted so that any desired compression may be obtained in the compression chamber. To arrest the inward movement of the piston and prevent injury to the stop ll byV forcible contact with the stuiing boX 13, I provide a lighter spring 14E around the pis.- ton rod between the said stop and the end of By placing the the st uliing boX. The cylinders, it 4will be noted, are arranged in series and that end of the cylinder from which the yoke l0 proi i jects may be termed the charging end while the opposite end may be termed the compression and explosion end, the charging end of one cylinder being connected with the explosion end of the other cylinder by a-pipe or conduit 15.- An inwardlyv openingvalve 16 is mounted at the end of the pipe 15 so 55 t wardly, the charge in advance thereof will as topermitflow through said pipe into the compression chamber and a similar valve 17 is mounted in thegcharging end of the cylinder to control the flow into the charging chamber. Each charging chamber is in communication with thefcarbureter through a supply pipe 18 which leads directly to the valve 17. A' spark plug-19 is provided in the explosion end of each cylinder and this spark plug may be of any preferred construction and will, of course, be connected with a timer and 'ignition system. The

' present application.

timer and ignition System, however, form no part -o'fmy invention and may be of any well-known type. I have, therefore, deemed it unnecessary to illustrate the same in the Leading into each end of eachl cylinder is a priming supply pipe v20 through wh-ich several parts of my improved engine being.

an initial charge may 4be fed into the cylinder from any convenient form of pump, the end of each of 'said pipes 20 being equipped with a valve 21 to permit flow into the cylinderand prevent iow therefrom.

TheA construction and .arrangement of the thusmade known, it is thought that the operation and advantages of the same will be readily understood and appreciated. Vhen it is desired tosta-rt the engine, a charge of fuel is pumped into each end of at least one c linder and a chargeis also um ed into the charging end of the other cylinder.

Assuming that the cylinderl shown at the left in' the drawing receives a charge of fuel in both ends and the cylinder shownat the right receives a charge only in the charging y end, which in the present instance, is the and an explosion will thereby be caused in the left-hand cylinder. The force of the explosion will drive the piston in said cylinder outwardly against the tension of the spring 12 and will immediately uncover the exhaust ports 6 so that the exploded gases will escape with v,f jreatvelocity and by their impact upon the vanes of the rotor will drive the same. When the -piston moves outbe driven through the. pipe 15 into the compression and explosion chamber of the right-hand cylinder while the charge at the lower end of said cylinder will be forced through the lower pipe 15 into the cylinder in which the explosionhas just occurred. Each charge in its travel will overcome the spring holding the valve 16 seated and willk also be slightly compressed against the charge has been transferred from one cylinder to the other cylinder, the spring 12 will expand and drive the piston inwardly so as to create a partial vacuum between the piston and the valve 17 whereby the said valve will be unseated and a charge of fuel drawn into the charging chamber from the carbureter.- The charge which is in the exp plosion end of the cylinder is, of course, compressed. The previously described operation will then be repeated and will continue automatically until the supply of fuel has been exhausted or is cut ofi' by the manipulation of the throttle valve in a wellknown manner. The timer and ignition system will be so arranged that the explosions will occur in the several cylinders successively and, consequently, there will be a continuous application of power. When an explosion Voccurs in any one cylinder, the charge of the fuel in advance of the piston in said cylinder will be driven into the next cylinder in advance and a charge will also be simultaneously drawn from the carbureter into the cylinder preceding the cylinder in which 'the explosion occurs.

It will be readily noted that I have minimized the number of bearings necessary for the production of an engine inasmuch as the/ only bearings needed are two bearings to support the rotor shaft. The only other moving parts are the pistons in the several cylinders and these pistons will move readily inasmuch as the power is not transmitted through the pistons and piston rods. The several valves employed may be of any desired construction and as they have a very slight movement, the frictional resistance to be overcome. at said places will bc of no importance. The several cylinders are mounted directly upon the rotor casing and the ports leading the gases from said cylinders are so ,disposed that the vgases will impinge directly upon the vanes ofthe rotor and, consequently, will act upon the rotor practically simultaneously with the explosion. rlhe several parts are evidently simple in their construction and arrangement and an engine embodying the invention may be produced at a low cost while the 11p-keep will be upon an economical basis.

i Having thus described the invention, what is claimed as new is:
